Title: Improvements in and relating to devices for closing doors and gates
IPC: E05F3/04
Filed: 1933-12-21
Abstract: 430,756. Door-operating appliances. COLLINS, A. L., Kennan's House, Crown Court, Cheapside, London.-(Cameron, E. M. ; 375, Smith Street, Durban, South Africa) Dec. 21, 1933, No. 36017. [Class 65 (i)] A collapsable or sliding door or gate is closed by a device comprising a cylinder containing a piston connected to the door through a linkage, the piston being acted on by a spring, assisted by the weight of the linkage, and moving slowly against the resistance of air in the cylinder until the stroke is nearly complete, when a byepass is opened to allow quick final closing. The device is shown applied to a sliding door, and the linkage comprises a member 17 pivoted to a fixed bracket 21, a member 18 pivoted to the door and, at an intermediate point, to the end of the link 17, and a member 19, pivoted at an intermediate point on the link 17 and having a slot engaging a pin on the end of the link 18. The cylinder 1 is pivoted to the link 17, and the piston-rod is connected adjustably to the lever 19. Opening of the door causes the linkage to rise and to draw out the piston, which compresses a spring (or two or more springs in series) in the cylinder, the closing movement being produced by the spring or springs assisted by the weight of the descending linkage. The closing movement is resisted by the air in the cylinder, which leaks out through a valve in the cylinder head, until the piston approaches the end of its stroke, when it passes the outer end of a byepass to allow free movement of the air and rapid completion of the stroke. The byepass may be formed by grooves in the cylinder, ports and passages in the cylinder wall or a short external pipe connecting ports in the cylinder.

Title: Improvements in or relating to the production of semi-conductor bodies
Inventor: BRADSHAW STANLEY EDWIN
IPC: C30B15/20
Filed: 1955-12-15
Abstract: <PICT:0808813/III/1> In a method of making a semi-conductor body by progressively solidifying a molten mass of silicon, a transition between regions with different electrical conduction characteristics is produced by evaporating antimony, previously incorporated in the molten silicon, during the solidification process.  In the embodiment a monocrystalline silicon body containing a series of PN junctions is produced by seed crystal withdrawal from a melt.  The melt 36 is contained in a fused quartz crucible 7 mounted on a graphite heating element 8.  Heat reflecting baffles 16, 17 surround the crucible and the whole assembly is mounted in a sealed enclosure 1.  100 grams of pure silicon is introduced into the crucible, the enclosure evacuated, and the silicon heated at 30 DEG  C. above its melting-point for a period to evaporate remaining impurities.  The seed crystal 37 is then dipped into the melt and the temperature adjusted to allow growth on the seed which is withdrawn at a rate of 1 mm./min. while slowly rotating.  The material crystallizing is high-resistivity P-type material because of a small residue of boron. A 20 mg. pellet of antimony is then added to the melt via tube 25 and crystal growth continued for a further minute during which only a small amount of the antimony evaporates.  The material crystallizing in this period is of low-resistivity N-type.  The growth rate is then held at zero or at a low value for 15 minutes during which the remaining antimony evaporates.  A further 1 mm. of P-type Si is then grown and the whole cycle of operations repeated any number of times. The antimony charge is slightly reduced on each addition to compensate for the dwindling size of the melt.  Bodies containing one or more PN-junctions may be cut from the resulting crystal.

Filed: 1934-12-20
Abstract: 453,933. Wrapping-machines. REPPMAN, A., and WOODWOOL WRAPPINGS, Ltd., 139, Queen Victoria Street, London. Dec. 20, 1934, No. 36562. [Class 94 (i)] A machine for enveloping bottles and the like in wood wool, straw, and other fibrous material, comprises a platform 7 adapted to be rotated by gearing 4, 5 from the main shaft 2. The bottle rests on a cushion 9 and is clamped in position by a cap 45. During the enveloping operation, the bottle is surrounded by a casing 11, made in two hinged parts 11a, 11b, Fig. 4, and adapted when brought together to be spaced somewhat from the bottle and to leave a slot through which the enveloping material may be fed. In use, the bottle is placed in position, and a pedal 32 is depressed to move a slide 23 to the left, Fig. 1. The sleeve is connected by links to square shafts 19, which through links 17, 18 close the halves of the casing. Further movement of the sleeve 23 causes it to abut a sleeve 25 on the spindle 24 and to move an arm 35 to clutch the driving pulley 3 to the shaft 2. The bottle is thus rotated and the enveloping material fed through the slot. One of the shafts 19 carries a plate 37 formed with a cam slot 37 engaged by a pin 39 on a lever 40. When the shaft 19 is rotated the lever 40 lifts a pawl 42 from a ratchet wheel 43 mounted coaxially with a pinion engaging a rack 44 which carries the cap 45, and allows the cap to fall to lock the bottle in position.

Filed: 1969-07-21
Abstract: 1280363 Digit checking device KOMBINAT ZENTRONIK VEB 21 July 1969 36603/69 Heading G4A Device checking numbers supplemented by a check digit alternately multiplies successive digits by 1 and 2, sums the products modulo 10 and uses two counters to form the products and sums. Digits successively supplied on lines L0 to L9 are coded using diodes Gr1 to Gr9 to a binary 16s complement value and stored in register A in bi-stable trigger circuits A1 to A4. The register stages feed an AND gate enabled when any of stages A1 to A4 is non-zero in generator G is enabled to supply clock pulses which count register A back to zero and produce pulses equal in number to the number stored. The clock pulses are fed to AND gates K6, K7 and are inverted in N1 and fed to AND gates K10 and K13 and via inverter N8 to AND gates K8, K9. Entry of data operates Schmitt triggers St1, St2 to switch bi-stable E at each digit entry to alternately enable AND gates K10, K11 and AND gates K12, K13. The pulses from generator G are thus fed to AND gates K6, K7 to increment a counter B and to AND gates K8, K9 to increment a counter C the counters being incremented by the trailing edge of the pulses. Inverted clock pulses are fed to one of the counters via whichever gate K10 or K13 is enabled by bi-stable E. The appropriate counter is incremented by the trailing edge of the pulse and so one counter receives two sets of pulses for that digit while the other receives one set. The counters count modulo 10 and feed AND gates K14, K15 via switches preset to correspond to the precalculated check digit. A circuit SK also adds a 1 to the counter effectively multiplying by 2 if the digit being multplied is 5 to 9 to distinguish between 2 Î 1 modulo 10 and 6 Î 2 modulo 10. The final result is taken from one of the counters such that the least significant digit is always multiplied by the same factor.

Abstract: 1363648 Photo-electric correlation apparatus AGFA-GEVAERT 20 July 1971 [29 July 1970] 36765/70 Heading G1A In order to detect variations in optical density or surface reflectivity of moving strip material or to measure the speed thereof, the optical density or reflectivity of the strip is monitored photo-electrically at two locations spaced with respect to one another in the direction of movement of the strip, the photo-detector outputs being correlated one with the other by multiplying directly the output signals and averaging the product value, a record of this average value being recorded while one of the detectors is moved. In one embodiment, Fig. 3 (not shown) the strip e.g. a photographic film travels from supply to take-up spools, guide rollers being provided therebetween and two transmissivity gauges being provided, each comprising a light source, optical system and a photo-resistor. The second of the gauges is moved stepwise or continuously, along the strip as recording proceeds. A second arrangement, Fig. 4 (not shown), includes a third guide roller. In an alternative construction, Fig. 5, the film 21 is passed round a crenelated roller. The fixed detector 17 is mounted in a groove and the adjustable detector 18 is mounted on an arm journalled to the smaller diameter roller. The detector 18 may be in the same or a different groove as detector 17, when autocorrelation or cross-correlation, respectively, is carried out on the detector output signals. The circuit for the detector outputs, Fig. 6, comprises amplifiers 31, 32 and equalizing amplifiers 33, 34 feeding a multiplying device 35. The product is averaged over a predetermined time by circuit 36 and recorded at 37, device 38 providing a signal indicative of the position of movable detector 18. In this way a correlation curve between the output at gauge 17 and the output of moving gauge 18 is built up.

Title: Improvements in and relating to aryl silicate heat transfer fluids
Inventor: BEANLAND ERIC
IPC: C09K5/10
Filed: 1963-09-13
Abstract: An aryl silicate composition is purified by heating it in the presence of a zeolitic molecular sieve and moisture at a temperature above 100 DEG  C.  When, e.g. 0.03 to 0.3% (by weight on the silicate) of water is used, little or no codensation will occur, whilst with increasing amounts of water, condensation will occur to an increasing extent.  In the examples, tetraphenylsilicate, from the direct reaction of phenol with Si, and containing unreacted phenol, was heated with C and a zeolitic molecular sieve to 200 DEG  C.; resorcinol containing water was slowly added and the temperature maintained at 200 DEG  C. for a further 20 minutes, after which phenol was stripped under reduced pressure with subsequent removal of solids by filtration, to yield a stable liquid silicate.  The starting silicate may be an orthosilicate containing phenyl, cresyl, xylyl or o-phenylphenyl radicals, or an aryl aryloxysilane such as phenyl- or biphenyl-triphenoxysilane.  Uses: the purified silicate, whether or not partially condensed, may be used as a heat transfer medium or may be converted to ethyl-silicate or -polysilicate.
